Article XX

Subject to the provisions of paragraphs 2 and 3 of this Article, the present Agreement shall apply only to the metropolitan territory of a Contracting Party.

Any State may, however, at the time of the deposit of its instrument of ratification or accession or at any time thereafter, declare by notification given to the Government of the United States of America that the present Agreement shall extend (subject, if the State making the declaration considers it to be necessary, to the conclusion of a special agreement between that State and each of the sending States concerned), to all or any of the territories for whose international relations it is responsible in the North Atlantic Treaty area. The present Agreement shall then extend to the territory or territories named therein thirty days after the receipt by the Government of the United States of America of the notification, or thirty days after the conclusion of the special agreements if required, or when it has come into force under Article XVIII, whichever is the later.

A State which has made a declaration under paragraph 2 of this Article extending the present Agreement to any territory for whose international relations it is responsible may denounce the Agreement separately in respect of that territory in accordance with the provisions of Article XIX.
